Draft, reply to, or analyse a legal notice (rent or service-charge demand, forfeiture or breach notice, statutory notice, letter before action). Every deadline is a calendar date with its arithmetic; every threatened consequence is confirmed and lawfully available; an admitted fact never concedes a legal conclusion. Triggers on "draft a demand", "reply to this notice". Does not fire on a whole-contract review (contract-review) or the output file's integrity (deliverable-integrity).
